COMBINATION GUN CLEANER AND SCREW DRIVER.

Application filed April 21, `1925. Serial No. 24,876.

To all whom t may concern:

Be it known that I, THORNTON SrLoo'rT, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in a Combination Gun Cleaner and Screw Driver, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to gun cleaners, such as are used for cleaning out the bores of rifles, pistols, revolvers, and other small firearms, and one object of the invention is the combination with a gun cleaner of a screw driver or similar implement, in order to enlarge the field of use of the device.

Another object is the provision of a combination gun cleaner and screw driver or similar implement whereby said screw driver or implement will provide a convenient handle for the gun cleaner when the device is used for cleaning guns, and so that the swivel portion of the gun cleaner is useful in connection withvthe screw driver or implement.

A further object is the provision of a novel swivel carried by the stock or body of the device for the connection of the cleaning rod to permit said rod to rotate freely.

A still further object is the'provision of novel means for connecting different cleaning rods with the swivel means, in order that different kinds and sizes of rods may be accommodated.

Still another object is the provision of a novel stop clamp to be used on cleaning rods to serve as a stop or gage to limit the movement of the rod into the gun barrel.

It is also an object of the invention to improve the ,gun cleaning device generally in its construction and details to enhance the utility and eliieiency thereof.

l/Vith the foregoingl and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the .Spirit et the invention.,

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the device showing the screw driver or implement blades used as a handle for operating the gun cleaner, and showing the adapter used for connect-ing the cleaning rod with swivel member. l

In carrying out the invention there is provided a tubular stock or body 20, which may be used as a handle when manipulating the device either as a gun cleaner or screwdriver or similar implement.V A U-shaped slide 21 is slidable within the stock 20 and its terminals are adapted to be projected from the rear end of the stock, and-a set of screw-driver or other implement blades 22 are mounted within the slide 21 between the arms thereof, being mounted for rotation side by side on the pvot nin or screw 23.

engaging the arms of the slide 21, so that when the slide 21 is projected from the stock the blades 22 may be rotated about a transverse axis. A set screw 24 is screw-threaded through the arms of the slide 21 near the inner end of the slide and is movable in a longitudinal slot 25 with which the stock is provided, said screw having a head 26 at the outer side of the slot 25 to permit the screw to be conveniently rotated. The stock 20 has the apertures 27 and 28 at that side opposite to the slot to receive the tip of the screw 24 in two .different positions of the slide.

lWhen the screw 24 is loosened so as to retract it from either of the apertures 27 and 28, the slide 21 may be moved rearwardly to projectit from the stock 20, and the blades 22 may then be swung around the pivot 23. The blades may be positioned at right angles-to the axis of the stock 20, as seen in Fig. 1, with lblades projecting' to opposite sides, and by moving the slide 21 -forwardly the blades are seated edgewise against the rear endY of the stock 20. The screw 24 will then register with the aperture 27 and when tightened will enter .said aperture to secure the blades 22 against the end of the stock so that said vblades provide a T-handle that may be conveniently grasped in the hand for manipulating` the stock or device when using the .device for cleaning a gun. The screw driver or implement thus provides a convenient handle.

lhenit is desired to use any one of the blades 22, the screw 24 is disengaged from the aperture 27 and the slide 21 moved outwardly. The selected. blade 22 Vis then swung to project rearwardly, while the other bla-des are swung forwardly7 withinthe slide 21. The slide is then moved forwardly into the steel 20, leaving the selected blade prejecting beyond the rear end of the stock while the otherv blades .are housed within the stock. The butt endportion of the selected blade is. within the stock so as to prevent said blade fromturning about the pivot 23. and the screw 24 is engaged into the aperture v28 so as to hold the slide 21a-nd blades 22 in position, Aas seen in Fig. 6.

The swivel at the forward end of the stock 2O comprises a bearing 29 fitted in the forward end of the stock and secured therein by'means of a screw 30` and a swivel inember having the shank or spindle'31 fitted rotatably in the bearing and provided with a head. 32 at the `outer or forward end. `The shank 31 projects rearwardly beyond the bearing 29 and a collar 33 is itted on the rear end portion of the shank 31 and abuts the rear end of the bearing 29 while the head 32 abuts the `forward end of said bearing. A screw 34 or other securing element is engaged into the rear end of the shank 31 and its head bears against the rear end of the collar 33, thereby anchoring the swivel member to the bearing. The collar 33 is suiiiciently long to space the head of the. screw 34 from the shank 31, thereby enabling the ends of the collar and bearing 29 to be iiled away from time to time in order to smooth the bearing surfaces. It' desired, ordinary ball bearings may be used between the bearing` 29 and the collar and head 32.

The swivel member or shank 3l provided at its 'forward or outer end with a screw-threaded socket 35` and said shank or member is provided rearwardly beyond the socket 35 with a screw-threaded secondary socket 36 of Smaller' diameter, in order to accommodate different cleaning rods, as seen in Figs. 4 and Thus, the socket 35 is adapted to receive the screw-threaded terminal 37 oi' a cleaning rod 33, while the socket 36 is adapted to Vreceive the smaller* screw-threaded terminal '39 of a cleaning rod 40 of smaller diameter. The rods 38 and 40 may be for 22 and 30 caliber' guns, respectively, or for other size gun bores. The swivel member will therefore accommodate different sizes of screw-threaded cleaning rods, and it will be `apparent that the red connected to the swivel member may rotate so that the patch or swab (not shown) on 'the tip of -the rod may Vfollow the ri tlings or" the gun bore, while the stock 20 and handle are reciprocated without turning, the swivel permitting the rod to rotate freely when it is reciprocated in the gun bore.

An adapter 41 is used 'for attaching the cleaning rods to the swivel member when said rods have smooth butt ends ,instead of being screw-threaded as shown in Figs. 4 and 5. The adapter 41 has a screw-threaded stem 42 which is threaded into the socket 35 ,so as to attach the adapter to the swivel member. The adapter has the primary and Secondary sockets 43 and 45, corresponding to the primary and secondary sockets 35 and 36 of the swivel member. The socket 43 at the forward end ot the adapt-er is of a diameter to receive the butt end oi a cleaning rod 44, corresponding with the cleaningrod 38, as seen in Fig. 2, while the socket 45, which is of smaller diameter' than the socket 43, is adapted to receive the butt end of a cleaning rod 4G ot smaller diameter, seen in Fig. 3, correspondingv with the cleaning` rod 40. The adapt-er thus accommodates smooth end rods, while the swivel member accommodates vscrew-threaded rods. rlhe adapter 41 has screw-threaded apertures 47 and 48 extending from its periphery to the respective sockets 43 and 45 to receive the threaded port-ion 49 of a set screw 50, and the threaded portion 49 is also adapted to screw into the socket 35 the same as the adapter itself. The set screw 50 has a head 5l and a threaded portion 52 between the portion 49 and head 51, and the socket 43 is screw-threaded to receive the portion 52 with the portion 49 projecting into the socket 45, as seen in Fig. 6.

When the rod 44 is fitted in the socket 43, the set screw 5() is threaded into the aperi ture 47 to clamp the rod, whe-reas when the rod 46 is fitted in the smooth socket 45, as seen. in Fig. 3, the set screw 50 is threaded into the apertui'e 48.

`When the device is used as a screw-driver or similar implement., as seen in Fig. 6, the set screw 50 provides a convenient pressure member to lit in the palm of the hand while manipulating or rotating the stock 20. Thus, with the adapter 41 secured to the swivel member, and' the cleaning rod detached, the screw 50 is threaded into the socket 43, and the face of the head 5l is conveXed so as to fit comfortably in the palm of t-he hand so that pressure may be exerted by the hand to hold the tool aga-inst the screw or other object operated o-n, while the vfingers of the hand or the other hand is used for rota-ting the stock 20, it being noted that the swivel member, adapter 4l and screw 50 do not rotate so that pressure may be applied while the stock is rotated. By removing the adapter 41 from the swivel member, the portion '49 of the set screw 50 may be screw-threaded into the socket 35 so that the screw 50 may be used as a pressure member in the same manner, and located closer to the stock.

The stop clamp 53 shown in Figs. l, 2 and 8 comprises a shell 54 of rectangular crosssection in which is slidable a core 55 of sim'- ilar shape, and said shell and core are provided with intersecting apertures 56 and 57. The larger apertures 56 are to receive the cleaning rods 38 and 44 of larger diameter, while the apertures 57 are to receive the cleaning rods 40 and 46 of smaller diameter. The apertures 56 and 57 extend transversely through the shell and core, and a screw56 is screw-threaded or otherwise secured in one end of the core 55 and projects from the corresponding end of the shell. A wing or other suitable nut 59 is threaded on the screw or stem 58, and the adjacent end of the shell 54 has an inturned flange 60 forming a seat for the nut 59. The-screw or stem 58 has a head 61 at its outer end to prevent the separation of the parts, thereby holding them assembled. When the nut 59 is screwthreaded toward the head 61, the core 51 may be slid in the shell 54 so that the apertures of the core and shell register, and the collar may then be readily slid on a cleaning rod and moved or adjusted to the desired position. Then, by rotating the nut 59 to screw it away from the head 6l, the nut 59 seating against the flange 60 will draw the stem or screw 58 outwardly, as seen in Fig. 2, to clamp the stop or collar securely on the rod. The stop clamp will therefore limit the movement of the cleaning rod in the gun bore, to prevent the patch or swab being moved through the opposite end of the gun bore. The stop clamp may also be used as a handle for rotating the cleaning rod to screw the cleaning rod into the swivel member or shank 3l.

As shown in Fig. 2, the core 55f hasv a screw threaded aperture 62 at that end op posite to the screw or stem 58, into which a set screw may be threaded to assist in fast eningthe stop clamp on the rod.

Figs. 9 and 10 illustrate a different form of stop clamp having the cylindrical shell 54a and core 55a, with a single aperture 56"x diametrically therethrough to receive the maximum size as well as smaller sizes of cleaning rods. A circular nut 59a is threaded on the screw or stem 53a of the core and seats against the flange 60L of the shell, said nut having a recess to receive the nut 61a, thus providing a neat appearance. The end of the core 55a opposite to the stem 58@ has a screw-threaded aperture 62a into which a set screw may be threaded if desired. The core 55e is prevented from turning by means of a screw or pin 63 engaged therein and working in a longitudinal slot 64 in the shell.

Fig. 11 illustrates another stop clamp wherein the shell 54b does not have a flange at the end thereof and the nut 59b seats against the end of the shell. A screw or pin 63b is removably engaged in the core 55b and works in` a longitudinal slot 64b in the shell. to prevent the core moving out of the shell and to limit the relative movement of the core and shell. y

Fig. 12 illustrates still another stop clamp or collar comprising the rectangular block 54c having the intersecting apertures 56c and 57c for rods of different sizes, and a set screw 59c is screw-threaded into the block to clamp a rod in either aperture.

Fig. 13 shows a stop clamp, which is of simpley construction, comprising a shell or tube 541 having rod receiving apertures 56, and a set screw 59d is serewthreaded into one end portion of the shell to clamp the rod, and the inner end of the screw is punched, as at 65, by a center punch, or is battered, so as to prevent the screw from being unscrewed out of the shell.
